This does not work if opponent or you made creature be sacrifed correct?
It does still work since a sacrificed creature still dies. To die is to be put into the graveyard from the battlefield.

I would just like to say that this is the first time for me to look at the rulings page. And it's rather impressive on the speed at which questions are answered! I know where to go from now on. *applause*
It combos well with Clone. You sacrifice the clone as a chump blocker and you copy something upon re-entry
